The Company recorded third-quarter sales of $178.2 million, an increase of 61 percent over the prior year, and 6 percent sequentially. Net income was $22.4 million, or $0.17 per diluted share. These results included amortization of intangible assets of $2.8 million.

Non-GAAP earnings per share of $0.18 in the third quarter of 2010 compared to a loss per share of $0.02 in the third quarter a year ago and earnings per diluted share of $0.16 in the second quarter of 2010. A reconciliation table of GAAP to non-GAAP earnings (loss) per share is contained in this press release.

For the first nine months of fiscal 2010, sales were $506.3 million, up 101 percent from the first nine months of 2009. Non-GAAP earnings per diluted share for the first nine months of 2010 were $0.48 versus a loss per share of $0.43 for the same period a year ago.

Gideon Argov, president and chief executive officer, said: "Our third-quarter results marked another quarter of growth and strong operating performance, as we continue to execute our growth strategies and build shareholder value. Sales to our core semiconductor market were strong, as our liquid filtration and gas filtration businesses achieved record-level quarters. Across our portfolio of technologies, we are capitalizing on an increasing number of opportunities with our advanced filtration and microenvironment solutions to help fab customers implement advanced sub-32 nanometer processes.

"Our adjusted operating margin was 18.0 percent, consistent with our target operating model. This translated into another quarter of strong cash flow, resulting in $45 million in cash from operations and $39 million of adjusted EBITDA in the third quarter. Our net cash
position is now approaching $100 million, well ahead of expectations. Thus far in the fourth quarter, demand from our customers is stable, despite the uncertain outlook for global economic recovery. Regardless of how this current industry cycle unfolds, we believe we have the opportunity to outpace our markets," Argov said.

For the fiscal fourth quarter ending December 31, 2010, the Company expects sales to range from approximately $173 million to $183 million. Based on the Company's target model, non-GAAP net earnings per diluted share are expected to range from $0.17 to $0.19.
